< cpp‎ | utility‎ | functional

Defined in header `<functional>` |  |
template<> class divides<void>; |  | (since C++14)

std::divides<void> is a specialization of std::divides with parameter and return type deduced.

### Member types

Type | Definition
`is_transparent` | unspecified

### Member functions

operator() | returns the quotient of two arguments (public member function)

## std::divides<void>::operator()

template< class T, class U > constexpr auto operator()( T&& lhs, U&& rhs ) const -> decltype(std::forward<T>(lhs) / std::forward<U>(rhs)); |  |

Returns the quotient of lhs and rhs.

### Parameters

lhs, rhs | - | values to divide

### Return value

std::forward<T>(lhs) / std::forward<U>(rhs).

### Example

Run this code

    #include <complex>
    #include <functional>
    #include <iostream>

    int main()
    {
        auto complex_divides = std::divides<void>{}; // “void” can be omitted
        constexpr std::complex z1{8.0, 4.0}, z2{1.0, 2.0};

        std::cout << std::showpos
                  << complex_divides(z1, z2) << ' ' << z1 / z2 << '\n'
                  << complex_divides(z1, 5.) << ' ' << z1 / 5. << '\n'
                  << complex_divides(6., z2) << ' ' << 6. / z2 << '\n';
    }

Output:

    (+3.2,-2.4) (+3.2,-2.4)
    (+1.6,+0.8) (+1.6,+0.8)
    (+1.2,-2.4) (+1.2,-2.4)
